Dell Inspiron 15R 5521 Battery
Your Dell Inspiron 15R 5521 battery allows you to move freely about so that you can use it wherever you fancy. Because no battery is the same, be sure to check the part number of the new battery and compare it to the old battery. The larger the battery, the longer you will be able to use the laptop when fully charged. It is OK to buy a battery with more milliamps, as it just means the battery will last longer. What is important is the physical size of the battery as well as the connection.
Main clues Dell battery has to be replaced
- The laptop does not run longer than one hour before it dies
- The battery has its case swollen like its about to burst
- The unit is unable to boot up at all when unplugged
